Transformation of Huangpi Jiangxia Pipe Network, Optimization of HDPE Winding Carat Pipe

The Core Pipe Requirements of Huangpi Jiangxia Pipe Network Transformation

In recent years, Huangpi and Jiangxia regions have accelerated the pace of upgrading the old urban pipe network. The original cement pipes and cast iron pipes generally have problems such as corrosion and leakage, insufficient drainage flux, and poor settlement resistance. In addition, the soft soil geology and complex underground acid and alkali media in some areas have put forward higher requirements for the weather resistance, sealing, and drainage efficiency of the pipes used for renovation. At the same time, construction efficiency must be taken into account to reduce the impact of renovation operations on residents' daily travel and business operations.

Performance Advantage of HDPE Wrapped Carat Pipe Adaptation to Transformation Scenario

HDPE winding carat pipe is made of high-density polyethylene as raw material, which is suitable for the multiple needs of Huangpi Jiangxia pipe network transformation: its ring stiffness covers a wide range, can cope with different buried depths and different road load usage scenarios, has strong resistance to uneven settlement, and is suitable for soft soil geological conditions in the area; excellent acid and alkali corrosion resistance, normal buried service life can reach more than 50 years, greatly reducing the later operation and maintenance costs; the smooth friction coefficient of the inner wall is small, and the drainage flux under the same diameter is about 30% higher than that of traditional cement pipes, which can effectively alleviate the problem of waterlogging in the rainy season; the overall weight of the pipe is only 1/8 of the same diameter cement pipe, and the transportation and hoisting cost is lower.

Type Selection and Construction Points of HDPE Winding Carat Pipe

When selecting the type of pipe network transformation, the HDPE wound carat pipe corresponding to the ring stiffness grade can be selected according to the buried depth of the laying section and the traffic load above, so as to avoid unnecessary cost waste. During construction, the electric hot melt or heat shrinkable sleeve connection method is used, and the interface sealing performance is good, which can completely eliminate problems such as sewage leakage and groundwater infiltration; the length of a single section of pipe can be customized to reduce the number of interfaces, and the construction efficiency is increased by more than 50% compared with traditional pipes, which can greatly shorten the renovation period and reduce the impact of road occupation construction on regional traffic.

Overall, the advantages of HDPE wound carat pipes in terms of comprehensive performance, construction cost, and operation and maintenance cost fully match the actual needs of Huangpi Jiangxia pipe network transformation, and are the preferred pipe materials for drainage, sewage, and rain water pipe network transformation scenarios.
